Patented Sept. 3,1907.

Application filed August 4', 1898. Serial). 68'L682- To all whomit may concern:

Be it known that I, LOUIS A.. CASGRAIN, of Winchestor, county of Middlesex, State of Massachusetts, have invented an Improvement in Machines for Inserting Faslenings, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates toapparatus employed in the manufacture of boots and shoes for the purpose of in sorting nails or other fastenings into the work, the latter being held upon a work-support or horn during the nailing operation. More specifically the invention relates to mechanism for controlling the position of the horn and for effecting its movements.

- While a fastening is being driven into the work the latter is firmly held or clamped between the horn and a cooperating prcsser, and I have provided herein simple and effective means for so controlling the horn that it will be automatically. moved away or lowered from the presser when nailing ceases, and maintained in such lowered position until the apparatus is set in motion to resume nailing. Such separation of the horn and presser permits the instant removal of the Work from, or application of the work to the horn with entire freedom, the work being fed over the horn after the insertion of each fastening in continuous nailing, the apparatus herein illustrated belonging to that type of nailing machine wherein the operator can cause a plurality of nails or otherfasteniugs to be inserted in the work inrapid succession, or stop the apparatus after a Singlefastening has been inserted. Such. control of the apparatus'is preferably effected through the medium of a suitable treadle,-and I have provided a device cooperating with "the horn controlling means to prevent premature lowering of the horn should the operator accidentally losecontrolof the operating mechanism before theproper time foreffecting the stoppage of the apparatus. The construction and arrangement of the horn has also been improved to include a connection between the .horn and the horn spindle which permits theEhQrn tobe moved on the spindle and carry the work laterally away'from the nailing devices to facili- 'tate its removal from the horn and the application of a new. piece of work in its place. I have provided stops 'to limit thisimovement of the h0rn=nndfllavesoloeated the connection that the horn will remain at restwhen' i which the horn spindle .is raised and the machine is started. The connection of the tipping means with the 'treadle'is such that'the horn is tipped into upright position at the same time that it is elevated, but it could be tipped into upright position before being raised if that were found desirable. The means which tips the horn also acts to lock it .in upright position so long as the machine is running and to unlock the horn to permit it to be tipped away from the nailing devices as soon as the machine is stopped. i

Various other novel features of my invention will be hereinai gr described in-the specification and pointed Fig. 1 is an inner side view of the horn and its support,-

looking to the-left, Fig.- 1. Fig. 2 is a side elevation of the lower part of thesupporting column or, standard, the lower part of the said standard being broken out to show more clearly the mechanism within it, the column being continued from the'upper part thereof shown in Fig. 1. Fig. 3 is an enlarged view in side elevation'and partly in section of the device shown in the lower right hand part of Fig. 2, for preventing the full descent of the horn before the proper time.

Fig. 16 is an outer endview ofthe hub of the member shown in Fig. 14. Fig. 17 is a detail, partlyinsection, of a throw-off device to be described, and Figs. 18 to 21 inclusive, are details to be hereinafter referred to, of a portion of the brake mechanism. I a 4 Referring to'Fig. 1, the head Act the machine is of suitable shape to provide bearings for the operative parts of the mechanism, andsaid operative parts, in cluding a presser and means for inserting fastenings in-the work, may beand are of substantially the construction shown and described in United States Patent #310816, dated January 13, 1885, the main driving shaft A having suitable bearings at A Fig. 1.

The driving shaft A has iast upon it a disklike memher A? provided with an annular, bevel'faced flange o ley A", sec Figs. 13 and 13, the disk and pulley thus forming the fast and loose members of a friction clutch mechanism. The loose pulley A is mounted to freely rotate upon and slide laterally on the extended hub a of'the fast member A,- and it is driven continuously by a belt from any suitable source of power not shown,

.the pulley having a suitable yoke a to engage an annu lar groove bin one'membcr b of the clutch controlling means, said member being shown as a sleeve mounted to slide longitudinally-on the main driving shaft A and connected therewith by aspliue b, Fig. 13. The

said member-l) is provided with a double cam-groov e. '6 the't wo parts of which are adapted to receive two roller or other studs 0 mounted in suitable bearings c on the other member 0 of the clutch controlling means,

recessed to receive the sleeve b said member e having an outwardly extended hub c rotatably mounted on a reduced portion as A of the main shaft, see Fig. 13, the

member 0 being held from longitudinal movement by the shoulder 3 and a collar A rigidly. secured to the shaft, as by a pin'4, Fig. 12. A strong spiralspripg S surrounds the hub c and is attached at one end tothe,

' collar A and at its other end by a pin or stud 5 to the member 0 of the clutch controller, the spring being wound in such a way as to normally tend to rotate the member 0? onor relatively to. the main shaft in the di rection of the arrow (1, Figs. 11 and 14. i i

The dou ble cam groove 1) in the member b of the i clutch controller is provided with diametrically opposite entrances b, see Fig. '15, to permit the entrance of the studs 0 in theassembling of the parts, and, as

shown in Fig. 12, the innerwall of the cam groove is provided with a high portion or shoulder b, it being understood that there are two such high portions or .shoiilders diametrically opposite each other to cooperate each with one of thestuds 01 rolls 0 One of the bearings c is cut away to forma seat for a preferably hardened steel block 0', suitably held in place as by a screw 7, Fig. 14, said' block forming a stop to cooperate at times with a detent d, Figs. 8 and 9,

preferably also madeas a hardened steel block and attached to the upper end of one arm (I of a bell crank lever," the said detent, when in the position shown in Fig. 8, engaging the stop c -and preventing rotationoi. the memherc v of the clutch controller.

Now, referring to 1 andilii, which show the T" clutch asinoperative, and supposing the direction oi drawnjrom engagement with the'stop c thespring S. will instantly turn the ,niember'c of the clutch con-. troller'on the shaft AX fromthe-position'shown ,inFig- 12, less than a quarter of a turn, to bring the studs c? into engagement with the cam-should'ers b", on the memqer b to thereby slide su'ch cooperating member of the clutch controller and positively move with it the pulley A, to the left, Figs. 12 and 13, to thereby, I

bring the friction surfaces a, a of the clut'ch members AZ, A into engagement and'effect the'operir'tiverota tion of the main shaft,.such rotation continuing as long such relativeangular position. When, however, the

.as the two members b 0 of the controller, remain in detentis brought into operative positionzto, and does engage, the stop 0 in its rotation, the relative positions of the members of the clutch controller will be changed instantly, and while the member c is of course'positively and suddenly stopped, the momentum ofthe bringing the latter into the position shown in Fig. 12,

parts connected with the mainshaft 11 will impart 5. :further partial rotation to the shaft and member b moving it and the pulley A positively to the right,

through the studs c" and cam groove b to'release the clutch members, and at the same time the spring S entered by a sliding stop pin c mounted in the collar' A as best shown in Fig. 17, said pin havingtwo-annu- 105.

lar grooves c therein, one or other of which is entered by a spring controlled locking plunger e mounted in a locking plunger holds the stop pin 0 either in its normail or inoperative position, as shown in Fig. 17,' or in .1 10

its inmost position, to enter, irl the latter case, the

, notch 11. This notch and-pin are so located relatively each to the other that when the stop pin pressed in -threadod stud c screwed into the collar A -'The to enterthe notch, the memberc cannot be turned by the spring S relatively to the shaft or to its1co6perating member b to throw the clutch members into operative engagement, evonthough the detent d is withdrawn from the step c. In otherwords, the stop pin 0 takes the place of the detent, and so long as rotative'movement of the controlling member 0 relative to the main shaft is prevented, the machine naybe turned over by hand as desired without any danger clutch is positiycly'movedbut of engagement with spring or springs to sepaand rapid in its action, whereas when dependence must be placed upon a spring to separate the clutch members the actionis slow and sometimes the clutch fails entirely to operate as desired. A

The arm d has a hub d through which is extendedloosely the long sleeve-like hub e of a lever arm E, see Fig. 18, iulcrumed. on a studE rigidly held in the head A of the machine, said lever arm E having at its upper end a roller or other stud e see Fig. 10, to travel onan' 30, 'whereat there is a quick rise to the circular part of the cam, which continues to the point 25, thus permitting the brake which is controlled by thiscam, as will be described, to be applied gradually and without sudden shock to the machine. connected to rock in unison by means of a suitable stud or pin 10, the cam 0 thus governing the movement of the detent d, and, by or through the' latter and the clutch controller, the operation of the clutch is governed. The periphery a of the clutch member A? is reduced in thickness and made substantially A-shaped, as shown in Fig. 13*, to be engaged by an interiorly and correspondingly grooved brake shoe, herein shown as made in twoparts b, b connected at their adjacent ends by a suitable bolt as b, the part 5 of the shoe being adjnstably connected by a link e with the depending portion or arm 0 of the lever E, the free end of the other part b' of the brake shoe embracing an eccentric sleeve 0'', shown separately in Figs. 20 and 21, longitudinally split and adapted to be clamped by a suitable bolt 16 onto the sleeve-like hub ,e of the lever arm E, as best shown in Fig. 18, and supporting the shoe.

Referring nowto Figs. 8 anda), it will be seen that, while the clutch is inoperative, owing to the position, shown in Fig. 8, of the detent d, the two ends of the brake shoe will be drawn together to tightly clamp the periphery of the fast member A of the clutch, the roll 0 then resting on the low portion of the cam G, as in Fig. 10, but when the lever arm (M is moved by the operator into the position shown in Fig. 9 to release the stop 0'' and effect operative engagement of the last and loose members of the clutch, as described, the lever- E will also be rocked so that the link 0 will move the part b of the brake shoe away from the clutch member A and at the same time the rocking movement of the lever arm E will cause the eccentric b to act upon the'surrounding end of the part I) of theshoe to move it away from the end of its fellow member I), separating part I) from the clutch member A so that the brake mechanism will be released at the instant the clutch becomes operative, and vice. versa, the main portion of cam O holding the brake off as the roll e travels thereon. A cam groove 0, Fig. 10, in the inner face ofthe clutch member A receives a roller or other stud 0 carried by a rocker arm C mounted'on the head A, see Fig. 1, said arm C having pivotallyconnected thereto 2. depending link C which extends down to the lower part 01' the supnected with a pawl carrier 0' adapted to slide in bear-- ings 12 and 14 secured to the standard, said pawl carrier The'lever arms d and E are having mounted thereon a toothed pawl 0 supported by parallel links c" and acted upon by aspring, herein shown as operating through a plunger c to press the toothed pawl normally into engagement with a correspondingly toothed rack d), also mounted to slide in the bearings 12 and 14, said rack being connected by a rod d" with a yoked 'pivoted at d to a lever D fulcrumed at D on the lower part of the standard. The inner end'of the lever Dhas pivotally connected therewith a link D extended up into the offset base portion A of the standard,-said link being surrounded by a horn lifting spring S" held between the bottom of the standard and a nut 15 on the threaded upper end of the link, said link forming one member of a toggle, the other member D being pivoted thereto at 16 and at its other end pivoted to the lower end of the horn' support, shown,

as a spindle D having a vertical bearing inthe upright extension A of the standard. A foot treadle F, also tached to or forming part of it a yoke F to which is rigidly secured an upturned arm F pivotally com iccted to the joint 16 of the toggle by a short link F extended through a suitable opening 17 in the standard, so'that depression of the end of the treadle F atv the front of the standard will act through the upturned arm F and the link F to positively straighten or set the toggle and thereby elevate the horn, which latter is mounted on the upper end of the horn support or spindle 11% as will be hereinafter described. The other or rear end oi the controlling treadle F is connected in a peei'iliar niann er, as will be described, toa rod d pivoted at its upper end to-the short arm a" of the arm 1%. i

When the operator has placed the work on the horn. he depresses the front 'end of the t-readle F and thereby elevates the horn to bring the work up against the usual presser foot P, Fig. Landat the same time the elevation of the rod (1 acts to swing the lever arm (I from stopping position shown in Fig. 8 into the position shown in Fig; 9, to efiect by the mechanism hereinbefore described the engagement of the clutch members and the consequent operation of the machine. The machine will continue to operate as long as the operator by keeping his loot upon the treadle F nmintains the clutch operative, and at every revolution of the main shaft the lever will be rocked, to raise and lower the pawl carrier 0 with a constant throw, and on ,its descent the pawl (2 will engage the rack bar d at the proper point, to (lepi'ess the horn as said pawlcarrier thereafter rises, such depression of the horn permitting the feed of the work, the general operation is shown in dotted lines as a trip (1, fulcrumed on the column at (1 and having a depending leg d, through an opening in which is loosely extended a threaded rod (F pivoted at d to the arm F said rod-having a check nut d thereon to adjust the movement of'the trip 11, the leg II and arm F being connected by a spring .9 to hold the leg against the check nut. 'Whenthe front end of the treadlc F is depressed to start the machine the movement of the upper end of the arm F to the g .left, against a spring S viewing Fig. 2, permits the spring s to throw the trip d to the right into the path of the pawl or one oiits supporting links c", and so long as the treadle 'is maintained depressed the trip will remain in such position and will release the pawl from the rack at each descent of the pawl carrier. This does-not interfere, however, with the. engagement of the pawl and rack at each ascent of the pawl, at a point corresponding to the thickness of the work, to thereby 1.0 lower the horn sufliciently to permit the work'to be i fed. -Inthe machine herein illustrated in which the work is fed by the awl, the horn is in its raised position While the roll.G Fig. travels in the cam groove C -from the point 75 to point 80, andithe. awl enters the g work. From 80 to about 8-1 the horn is lowered, and

the feeding movement of the awl occurs while the horn is down, from about the point 81 to point 82, and as the Irorn is rising as the roll travels in the cam groove to point 83 the awl is withdrawn from the work, the

spring S raising the horn while the toggle remains set. When the. treadleFis released and the toggle is therea upon broken by the action of the spring S 9, thead' justable projection or nut d on the threaded rod d? acts to positively move the upper end of. trip rPto the left, or

into'the position shown in Fig. 2, so that the pawl at the lower end of its stroke will not bedisengaged from the rack as the machine is brought to a stop. Such withdrawal of the trip d? is necessarywhen the machine is stopped, for the pawl and rack must then the locked 0 together to resist, vthrouglri' thelever D and rod D, the action of the horn lifting spring, so that when the toggle is broken the horn'will descend. Were not the rod'D so held againstthe lifting action of the spring the latter would operate to elevatethe horn upon stoppage of the machine.

Obviously the horn must be maintained elevated with certainty during thenailing operation, and to prevent premature breaking of the toggle, such as 'would be caused by a release of the treadlel below 40 the proper.tirne, Thave'p'rovi'ded'a locking device,

- which is shown as forming a part of the connection ofthe rear end of the treadle with the rod d3, such connection permitting at times movement of the treadl'e relatively to the rod. This rod d passes through a fixed 4 guide 25 secured to or forming part of thebearing 152 for the pawl carrier, and is threaded at its lower end To receive an adjustable socketed collar d between whi h and the guide 25 aspiral spring S surrounds the llrd to normally depressthe latter and maintain the detent d in operative position, the lower end of the spring I entering the socket.

i The lower threaded end-'of the rod d has screwed upon it a foot f having a longitudinally'slotted or bifurcated end f 'to embrace a lateral stud 30 mounted 5 in the treadle F near its r.ea'r end, to permit setting of the toggle before the machine is actually started.

Said foot has'two laterally extended lugs'f' and f v thereon, Figs. Sand 4, substantially at right angles to each other, the former supporting the fulcrum pin f of aloe king dog f shouldered at f a to engage an opposite shoulder 33 on the, extremity-oi the treadle F, a spring s held in thechambered head f of the (log endibe'aring against the lug f tending to maintain the-dog inoperative position. An internally threaded earf on the dog'receives a threaded depending "standard.

purpose an auxiliary treadle H is provided, iulcrumed stud j? which at its lower end bear-son ahead deli or projection f mounted on one of thelegs'usA of: the

Referring to Fig. 3, it will be seen that the stud 30 isnearthe upper end of the slotted end of thefoot f and that the shouldered dog f 5 is in'engagement with the shoulder 33 of the treadle F, and,'itbeing remernv "bered that the cam Oindirectlycontrols the descent of the rod d it will be obvious that so long as said rodv is held froin descending, it will, through the dog f prevent the return of the treadle F to normal position even should the foot of'the operator be removed there-, from. It, therefore, with the parts in the position shown in Fig. .3, the operator removes his foot from the treadle tob soon, the toggle will not bebroken, but will be maintained set or straightened until thedcscent of the rod d. causes the lower end of the adjustable stop f then in iengagement with the cam or inclined lace of the stud f, to slide over such face and swing the dog f 5 on its ,lulcriiin and withdraw the shoulder f from engagement withthe shoulder 33 on the tr'eadle, and the latter is then free to return to normal position.

It is sometimes desirable to depress the horn independently of the operation of the machine; and for this at D and-having a toe H'- see dotted lines Fig. 2, extended beneath the part of the lever arm D back of the fulcrum,- so that when the -treadle H is depressed, the lever'D will be-"tipped to depress the horn against the action of the spring Sf. i

The upper end of the horn support or spindle D passes through thebearing A, and has clamped thereupon a split sleeve h, see Figs. 1 and 1, said sleeve having i'ulorunied thereon ....b a yoke h also shown as split at its upper end and adapted to receive the shank of the horn H and to be clamped upon said shank by a'suitable clamp screw or bolt h l The yoke and attached horn may thus be swung about the fulcrum h into or out of operative position, the former being shown in Fig. 1, and I prefer to provide protecting lips 40 and 11 at the front and rearot' the yoke toprevent the entrance of chipsor dirt to the part of the mechanism therebelow. The inner wall of the lip 41 contacts with the adjacent face of the sleeve h, acting as a stop to arrest the.n10verne nt of the horn when itreaches operative position One of the yoke arms is down- 'wardly extended as at h, below its fulcrum, and the face h thereof is adapted to be engaged by the rocker arm h mounted on the bearing A", and connected by link h with the'treadle F. The rocker arm h orms a stop tobe engaged by the face h,and limit the outwardtipping movementof the horn. The fulcrum h is so located with relation to said stops and to the cen ter of gravity of the tipping horn that said horn will remain at rest in either its upright, operative position shown in Fig. 1, or in the inclincdposition to which it may be tipped. -When the treadle F is depressed, the rocker arm. h is turned by the link h to bring its-free. end or eccentric portion into engagement with the lace ll of the yoke andtipthe horn into upright position, and thereafter said arm holds or locks the horn 'positively against any rocking or swinging movement until the trendle is released. whereupon the locking device It is turned into the position shown in Fig. l, and the horn is free to be moved. The iaceh is of sulficient length so that thetrocker arm h may slide thereon as i the horn is raised'and lowered to clamp and unclarnp the work for feeding while. the horn is locked against tipping' movement. Prom lhi's descriptioiiit will be .5 understood that when the nailing of a piece of work is completed'and'themachine is stopped by the release or the treadle F, therocker armh? occupies the position shown. 1, and the operator in removing the work from the horn may tip'the horn outward to carry the work iaw'ay from under the driver and the presser P,'

where can, be easilypulled off the horn. v This capac- 'ity of the horn for movement laterally away from the nailing mechanism is of .particularadvantage' when V relatively thin work, such asheel seats,is' being nailed, 1 5 because it'is desirable that the depression'oi the" horn to, permit the removal of such work be very slight, varying from one-eighth tonne-fourth r an inch, and if the horn Werenot laterally movable it would often be difii- ,cult to remove" and apply the work quickly. When- 120. the horn' is tipped away from the nailing devices the removes time work,lit remains in'such position because oithfe location .oftthe fulcrum h, When a -new piece'oi ,work has been putin place on the horn, the depression of the treadl'e E'acts through the toggle to elevate the horn spindle a'rid horn, and simultaneously operative position in advance of the starting of the ma- }fichine so that-there is no danger of a fastening being driven before the Work is in position toreceive it.

v I havealso devised a simple and effective work gage adapted to engage the upper of the boot or shoe near the sole, the upper being preferred because of the irregularities which are apt to occur in the edge of the sole.

" Figs. 5 and-6 are enlarged views of the work gage shown inpositionv in Fig. 1, said work gage comprising a work-engaging member inrthe form of a truck-or roll 4 m preferably having a periphery m of some soft or yielding material as iclt, rubber, etc., the roll being rotatably mounted on an arm m provided with a hub .m through which is extended a shouldered bolt m, sec

' Fig. 6, the reduced portion of the bolt passing through a lateral bearing'm in a plate, or bracket m, adapted to be boltedto the usual gage carrier R, see Fig. 1:.

" The gagecarrier is adjustable to vary the distance be tween the gageand the driver of the machinefto determine'the distance from the edge at which the nail v or other fasteningwill be inserted. One end of a spring 3 is held in a housing m on the bracket m", the other end oi the spring extending beneath a log m on the arm m, to normally elevate the roll or gage m. Referring t'o Fig. 5, the bracket m has a depending por- 9 tion m fwith its' upright edge notched at m to receive one of a series of stops 50, 51, 52. I have herein shown these steps as ears of different Width mounted on a combinedclamping and supporting bolt m As shown in Fig. 5, the narrowest one of the ears 50 projects in to the a fastening into -the work.

notch m so that the greatest vibratory movement of the arm m'" is permitted, it being obvious that the ears are carried by the arm m. The car 51 is a little wider than the car 50, and permits less movement of the arm m,-while the widest ear52 is so wide that the very slightest vibration of the work gage is permitted.

The adaptability oi the work gage to move up and down is of advantage in that it permits the gage tornove with the work as the latter follows the up and down movement of the horn, and the spring .3 is very light, merely strong enough to retain the work gage in operative position. v

. I'have herein described one practical embodiment of my invention, but do not restrict the invention to such construction. and arrangement of parts, for the construction may be varied or the parts rearranged or any of the combinations defined'in the claims may be used separately without departing from the spirit and scope of my inventionj i I While I have "herein shown and described a workgage to engage the upper of the boot or shoe near the sole thereof, such work-gage is not made the subject of a claim herein, except in combination'with other mechanisms of the machine, as the gage itself forms the subject matter of'and is duly claimed in adivisional'apph cation serial N0. 120044,-fi1e 1-b me on the lfith day of August, 1902.
